What To Do
• Remove knob by pulling it straight off the stem and
check the bottom of the knob for any build-up of soil.
• This is a typical electrical switching noise.
This is normal.
• See Care and cleaning of the cooktop section.
• See the Care and cleaning section.
• See Flames too high or too low at the LOW setting
in this Troubleshooting Tips section.
• To turn from the OFF position, push the knob in
and then turn. The knob can only be turned in a
counterclockwise direction. When the knob is at any
other position, it can be turned in either direction
without being pushed in.
• Check connections. Turn on power at the fuse box.
• This is normal. The fan comes on automatically
when the grill is in use.
• Clean filter per instructions.
• Open a window slightly to provide fresh air source.
• Remove blockage from exterior wall cap.
• Check exterior wall cap damper door for free movement
or obstruction.
• Reduce number of elbows to simplify duct run.
• See the Care and cleaning section.
• Cover pan with a lid.
• Turn the downdraft fan OFF until the water begins
to boil.
